The backend URL would need to look like the following
/bar/?searchState=ca&searchCity=marina+del+ray&firstName=first&lastName=last

As you can see for the city I need to replace the "-" with "+"

Any assitance would be greatly appriciated, I would like to be able to make this rule dynamic enough that if a city name contains 1 or 15 words it will still tranfer over without having to create 15 seperate rules for each permiation.
